Source: Data are based upon Bureau of the Census report Form MA—28E.1, Annual Report on Shipments and Production of Inorganic Chemicals. STOCKS Consumers inventories of bauxite increased during the year, but stocks at mines and processing plants declined sufficiently to account for a net decrease of 3% in total industry inventories. Government stockpiles were reduced 4%. About 586,000 long tons of Surinam-type bauxite was shipped from Government defense inventories and an additional 110,000 tons of bauxite was shipped from a Government stockpile accumulated during World War II. Total inventories of alumina and related products at plants producing alumina and primary aluminum were 1,079,000 short tons on December 31, 1972, virtually unchanged from 1971 yearend stocks.

PRICES Market prices for domestic crude (undried) and dried bauxite were not published. Bureau of Mines estimates of the value of bauxite production were based on data supplied by producers. Data for most of the crude bauxite came from companies which produce ' bauxite for their own use rather than for sale. The Bureau estimated the average value of crude domestic bauxite shipments in 1972, f.o.b. mine or plant, at $10.60 per long ton. The average values of shipments of domestic dried and calcined bauxite were estimated at $14.39 and $338 per ton, respectively. Bauxite values among producers varied widely because of differences in grade. The average value of imported dried or partly dried bauxite consumed at domestic alumina plants was estimated at $14.79 per long dry ton, compared with $14.39 (revised) for 1971. During 1972, Engineering and Mining Journal published the following prices on refractory-grade bauxite, carlots, Atlantic ports, per long ton: January- October— September December 87.75% minimum A1IO3 88% AllOl (super calcined) - - $47.50 51.00 $47.50 60.50
